NGC1491 Also known as LBN 704 or SH2-206. It is a wide and bright emission nebula in Perseus.
Its name - Fossil Footprint Nebula - comes from wide-field images, where this nebula looks like a giant cosmical footprint.
Its intense and predominant red color is due to the Hydrogen which is very abundant in the nebula and it is energized by hot stars within it
